You can definitely adjust the opacity by setting the alpha value. Interface Builder lets you edit the value directly, but in code I think you would do:

[[myActionSheet view] setOpaque:NO]; 
[[myActionSheet view] setAlpha:0.5];

I'm not sure if you need the setOpaque call or not - I think that is used to help optimize performance, as the iPhone won't try to render anything hidden by the opaque view.
